Construction of Superstructures with One-dimensional Inclusion Space based on Dehydrobenzo[12]annulene Derivatives

Abstract

Dehydrobenzo[12]annulene (DBA) derivatives are attractive molecules as building block cores of supramolecular assemblies, which are expected to exhibit optical and/or electrical functionality. In connective with this, we performed construction of crystalline supramelecular assemblies with inclusion space by using C₃ symmetric DBA derivatives with polyaromatic substitutes. As a result, the crystals with one-dimensional inclusion space around the stacked DBA molecules were obtained. We report the detail of the crystal structures and structural conversion of the DBA assemblies through guest molecules desorption and insertion.
